Slide 1 INPUT – PROCESSING – OUTPUT
Slide 2 INPUT – PROCESSING – OUTPUT A key part of writing programs is to be able to identify what steps to take and in what order to take them. For your programs, each instruction (statement) can be identified as input, processing or output. When you are asked to write a program to perform a certain task, you will need to identify the key elements and categorize them as Input, Processing or Output. This takes practice! Let’s get started!
Slide 3 What is Input, Processing, Output? Ask Yourself…
Does it describe how the information should be displayed for the user to view? That is OUTPUT
Slide 4: Problem 1:Calculate Mr. Blue’s wage when given the number of hours worked (23) and his hourly rate of pay ($5.25). The output should be in sentence form stating his name and wage.
Slide 5: Problem 1 (INPUT): Calculate Mr. Blue’s wage when given the number of hours worked (23) and his hourly rate of pay ($5.25). The output should be in sentence form stating his name and wage.
Slide 6 Problem 1 (PROCESSING): Calculate Mr. Blue’s wage when given the number of ours worked (23) and his hourly rate of pay ($5.25). The output should be in sentence form stating his name and wage.
Slide 7 Problem 1 (OUTPUT):Calculate Mr. Blue’s wage when given the number of hours worked (23) and his hourly rate of pay ($5.25). The output should be in sentence form stating his name and wage.
Slide 8 On the following slides, read the steps described and determined if it would be part of the Input, Processing or Output.
Slide 9 Question: 1 Determine the Hummer’s Miles per gallon during your summer vacation trip.
Slide 10 Question: 2 While driving your Hummer, you use 50 gallons of gasoline to drive 300 miles for your summer vacation to the Smokey Mountains. A = INPUT

Slide 17 Question: 9 Find the rate the geese were traveling. Use the following formula: rate = distance/time A = INPUT
Slide 18 INPUT – when assigning the raw date you know to variables, us LET. Soon, you will learn another key word, INPUT. PROCESSING – when performing calculations, use the LET statement to assign the results to a numeric variable.
